Abstract

The invention discloses a sports shoe sole material with high wear resistance and high shock absorption and a preparation method thereof, and relates to the technical field of sports shoes. The high-wear-resisting and high-shock-absorbing sports shoe sole material disclosed in the present invention, under the action of a cross-linking agent and modified nano-zinc oxide, utilizes PBSs to modify EVA to cross-link and blend to form an EVA / PBSs copolymer, which is then mixed with polymer It is prepared by blending raw materials such as ester thermoplastic polyurethane elastomer, waste rubber powder and modified diatomite, and molding and foaming. The sports shoe sole material with high wear resistance and high shock absorption provided by the invention has the advantages of simple preparation process and easy operation, low density, high elasticity, excellent wear resistance, shock absorption, weather resistance and corrosion resistance, and improves the The comfort of sports shoes, prolong the service life of sports shoes.

Description

technical field [0001] The invention belongs to the technical field of sports shoes, in particular to a sole material for sports shoes with high wear resistance and high shock absorption and a preparation method thereof. Background technique [0002] With the rapid development of modern society, people's concept of wearing shoes has undergone great changes. From the protection and heat preservation of the last century to the pursuit of lightness, comfort, beauty, shock absorption, wear resistance and other functions. As the world's largest producer and consumer of sports shoes, China's research and development of sports shoes is also changing with each passing day. Existing sports soles are divided into three categories: vulcanized rubber soles, air-cushion filled soles and foam soles. With the continuous development of science and technology, foam soles have the advantages of both excellent performance and low cost, occupying a relatively high place in sports soles. large ...
